Abstract
The invention discloses an assembly method of a display module and the display module. The display method specifically comprises the steps that a display panel and a rubber frame are assembled and located so that a sub assembly can be formed; an optical film, a light guide board, an LED lamp strip and a reflector sheet are sequentially assembled above the sub assembly. Firstly, the rubber frame and the display panel are assembled and attached and secondly, the optical film, the light guide board, the LED lamp strip and the reflector sheet are assembled in sequence. Due to the fact that the display panel has certain rigidity, after the rubber frame is attached to the display panel through frame sealing glue, certain mechanical strength can be achieved, deformation and dislocation which are caused by locating pressing combination can be effectively avoided in the process of film assembly, the assembly difficulty can be reduced, the assembly periodic time can be shortened, the assembly efficiency can be improved, and the reject ratio of the products can be reduced through the adjustment of the structural design of the LED lamp strip and the rubber frame.
Description
Technical field
The present invention relates to technical field of liquid crystal display, relate in particular to and be a kind ofly applicable to without the assemble method of the demonstration module of back board structure and apply this assemble method and assemble the demonstration module obtaining.
Background technology
Along with developing rapidly of international information technology (being IT) industry, as the demonstration product of the mobile terminal of mobile phone, computer, notebook and other types, impel LCD(Liquid Crystal Display, liquid crystal display) industry also constantly weeds out the old and bring forth the new, LCD product size is towards the high development of diversification and lighting side, backlight module (Back Light Module, be called for short BLU) as one of core component of LCD product, certainly will coordinate this development trend, be devoted to diversification and the lighting of product.
Current existing LCD demonstration module (LCD Module is called for short LCM) assembling flow path is generally assembled separately back light module group by backlight module production plant, then by the assembling LCM of LCM production plant module.Backlight module is generally divided into two kinds, and a kind of is the backlight module that has backboard, and another kind is the backlight module without backboard, for having the backlight module of backboard owing to there being the support of backboard, can rely on backboard to offer help to glue frame and film material location in assembling processing procedure.Without the assembly model of the backlight module of backboard as shown in Figure 1, assemble successively glue frame reflection subassembly 1, light guide plate 2, LED lamp bar 3, three layers of optical film material 4-6 and sealed plastic box 7, glue frame reflection subassembly wherein 1 is exactly structure glue frame and reflector plate being bonded together with joint strip, after assembly backlight module has been assembled, according to the backlight module 10 shown in Fig. 2 and the schematic diagram that display panel 20 is assembled, assemble again, by LCD, complete whole assembling processing procedure.
In the backlight module assembling process without back board structure shown in above-mentioned Fig. 1, will there is following defect: owing to there is no the support of backboard, bringing great difficulty to follow-up glue frame and film material location, assembling, there is larger difficulty in each number of assembling steps, and yields is lower.Because glue frame is thin and soft, in assembling contraposition process, be difficult to find positioning datum, and in film material assembling pressing process, glue frame contacts with pressure head, is easy to cause glue frame be squeezed and be out of shape.So just to backlight module assembling processing procedure, bring many adverse effects, as assembly operation difficulty is large, the assembling cycle time is long, packaging qualification rate is lower etc.
Summary of the invention
(1) technical matters that will solve
For above-mentioned defect, the technical problem to be solved in the present invention is the assembly operation difficulty how reducing in making without the BLU assembling of back board structure, improves the yields of product.
(2) technical scheme
For addressing the above problem, the invention provides a kind of assemble method that shows module, comprising:
Display panel and glue frame are assembled and located, composition sub-assembly;
Above sub-assembly, assemble successively optical film material, light guide plate, LED lamp bar and reflector plate.
Further, described to display panel and glue frame assemble and position fixing process in use sealed plastic box that display panel and glue frame are bondd, realize location.
Further, described optical film material is close to glue frame and is assembled.
Further, described optical film material comprises trilamellar membrane sheet, is followed successively by diffusion sheet, upper brightening piece and lower brightening piece.
Further, after optical film material top assembling light guide plate, the sub-assembly marginal position after assembling optical film material and light guide plate arranges LED lamp bar, and is electrically connected with driving circuit.
Further, described LED lamp bar is arranged in the groove of light guide plate side.
Further, described reflector plate covers the top of light guide plate and LED lamp bar completely.
For solving the problems of the technologies described above, the present invention also provides a kind of demonstration module, the demonstration module that wherein said demonstration module adopts the assemble method of above-described demonstration module to assemble to obtain, comprise backlight module and display panel, wherein said backlight module is the backlight module without back board structure.
(3) beneficial effect
The invention provides a kind of demonstration module obtaining that shows the assemble method of module and adopt this assemble method to assemble, wherein assemble method specifically comprises: display panel and glue frame are assembled and located, composition sub-assembly; Above sub-assembly, assemble successively optical film material, light guide plate, LED lamp bar and reflector plate.Above-mentioned assemble method is by first glue frame and display panel being assembled to laminating, then carries out the assembling of optical film material, light guide plate, LED lamp bar and reflector plate successively.Because display panel has certain rigidity, glue frame has certain physical strength after sealed plastic box and display panel laminating, can effectively avoid the distortion and the dislocation that in film material assembling processing procedure, because of location pressing, cause, thereby reduce assembly operation difficulty, shorten the assembling cycle time, improve packaging efficiency, reduce the fraction defective of product simultaneously, by adjusting LED lamp bar and adhesive frame structure design, the lamp bar assembling feasibility that not only can guarantee backlight and LED, still guarantees the minimized assembling feasibility of LED exiting surface and light guide plate incidence surface gap simultaneously.
